I really like this image. I love the core with the orbiting electrons combined with the compass. Although I tend to thing that compasses are a bit overdone in logos I do like this image. (I like that this image is crisper then the other)
Could an arrow be a symbol of reaching your goals? Everyone is given a limited number of arrows. Use your arrows wisely and aim for what you really want. Once your arrow has been shot, there's no going back but you have one option: move on.
